Serial no. s42,ee2.

This invention relates to' suction cleaner tools, both'of the ordinary,as Welles of the air-way type.

- The objects of theinvention are to'p'rovide I a lint-removing orthread-picking attachment to such tools, to provide such tools w th anautomatico'penlng and closing means for the ends operating.intermittently, and to produce vibration in such tools, and to produceother novel results as may appear in this specification and claims.

To these ends, the inventlon may conslst of a construction, arrangementand comb nation of parts as set forth and illustrated in theaccompanying drawing, in which,

Fig. 1 shows a longitudinal crosssectlon of the cross-head-of a suctiontool, to which the floor tool is pushed bac and forth over -nyimprovements are attached;

Fig. 2 is an under-side or bottom view of such cross-head with saidattachi'nents;

' Fig. 3 is an end view taken at right angles;

to that of Figs. 1 or 2, particularly portraying the improved form ofrubber-capped roller'to he e'mbodied in the invention, and.

75 V Fig. 4 is a View partially in cross section through the middle ofthe cross-head with the threadpicking attachment inserted.- Referringtothe drawings, the cross-head 1 having the open interior 2 communicatingpieces 4 and l having lower edges fcoplanar and adapted to contact withthe surface-or carpet 5 to be cleaned.

At each end of the body 1 is a roller '6 mounted in a shank 7 having aspring 8 adapted'to al1ow.of a yielding vertical mo;

tion of the mounted roller, and the shanks also carry end lids 9, 9secured to the shanks I at 10, 10, whereby vertical movement of the fromthe end openings 9, 9' between-the ends .of the coplanar lips of thepieces 4, 4'. The rollers used in thiscase are special; they arepreferably constructed of resilient rubher and have a series of frets orprojections 6, 6', 6", etc.,= on their peri heries. These frets aredesigned to cause vi ration upward and downward of the lids 9, 9,. or ofthe tool itself, or both, as modified by certain circlunstnnceshereafter referred to.

with the suction pipe 3v is provided with. lip

roller in one'dijrection will remove the lids" Besides the rollerattachments referred to,

the interior of this floor tool may be provided with a thread-pickingdevice constructed preferably from resilient wire 11,

recurved as at 11,- and having its ends 12,

12 pivoted at the top of the interior of the tool; The lower part ofthis wire,' which is coplanar with the lips of the tool, is providedwith a cushion 13, preferably constructed from rubber tubing slippedover the wire. The thread picking element-may side arms of the wire .11,thus drawing its ends 12 out of their sockets. i

In the operation of the device, the threadpicking device isalternately"pressed against the coplanar parts of the li pieces 4, 4',as

be understood-that if the body of the tool is pressed downso that vthelips are pressed flat against the'surface to be cleaned, then thefrets-6', 6,j- 6' etc. will cause the lids to be lifted intermittently,as the rollers travel with a Jumping motion. If, however, the

vbe removed by simply pressing inwardly the operator presses onlylightly downwardly on tool'the bodyxof the tool will be found to vibrateslightly with reference to the floor. i

Having; thus described a preferred con- 'stru ction and mode ofoperation of the device, this specification is not intended to berestricted to the exact constructions shown, as many modifications ma beemployed within the scope of the appen ed claims. I

I claim: j

1. In a floor tool having floor engaging lips and having tool endopening and closing means, means for operating said opening and closingmeans, a swingin element within the body of the tool, and having acushioned portion thereof coplanar with the lips of the tool and adaptedto impinge against the in-' terilor of either lip in the operation 'fofthe 2. In combination with a pneumatic clean- 5 ing tool having endopenings, end rollers 'for' said tool, roller shanks resiliently mountedin theends of said tool for supporting the tool on the rollers, lids forsaid end openings carried by said shanks, and peripheral projections onsaid rollers adapted to cause vertical movement of the lids during theoperation of the tool, for intermittently opening and closing said endopenings, and a thread picking element swingingly mounted within '5 andadapted to engage a portion of the mouth of thetool.

3. In a floor tool having floor engaging lips, and having end openings,means'for automatically and intermittently opening and closing said endopenings during operation of the tool, and .a swinging .elemen't pivotedwithin the body of the tool, said element having a thread pickingportion substantially coplanar with the lips of the tool 5 andlswingablefrom side to side to contact with one or the other of said lips.

4. A floor tool having floor enga ing lips and having-end openings,means or automati'cally opening and closing, 'said end openso ingsonmoving said tool over a surfaceto be H cleaned, and means swinginglymounted within the body of the tool and coacting with the H s of thetool for grasping threads or;

thelie.- 3'5 5. A floor cleaning tool having floor engaging lips andhaving end openings,means forautomatically opening and closing said endopenings on moving said tool over a surface to be cleaned,.incombination with means .0 coacting with the lips of the tool forgrasping, free threads or the like on the article to be cleaned, saidthread, grasping means comprisingban elementswinging y mounted with- Iin the ody of: the tool so asto contact with .one or the other lipof'the tool.

y 6. In a cleaning tool, a thread picking ele-v, ment consistingof amovablebar arranged within the mouth of the tool, adaptedto be pressedagainst a lip thereof so as. to grasp no threads anddhe like betweensaidbar and lip, and"meansxfor'detachably ,supportin said bar'withinthe bodyof the tool, sai

means comprising resilient curved arms ex-- tending 'w'ardlyv from themovable bar, said at arms beih g bent outwardly at their upper,portions, said-outwardly bent portions being yieldingly engaged within.the body of the In testimon whereof I aflix si ature. DAN IIL BENSON RELO LE.
